Please help I’m confused

Glow says I should have ovulated on the 26th I had ewcm on the 26th so I thought it was correct. My husband has been out of town so I thought we were out this month but be surprised me and came home on the night of the 27th. We DTD that night and yesterday morning but I still though we were out since it was past ovulation. But today I went to the restroom and had a ton of ewcm (more than I did on the 26th). Am I ovulating now? Is there a chance? Is my app incorrect? My AF was on 12/13/14 and is normally those days every month.
